To all whom it may concern Be it known that I, l/VENDELL Huss, Jr., a citizen of the United States, residing at T roy, in the county of Rensselaer and State of. New York, have invented certain new and useful Improvements in Scales, of which the following is a specification.

This invention relates to measuring instruments and particularly to a device intended to measure and interpret continuous records plotted by a recording device.

Certain features of the device are such as particularly adapt it to the interpretation of records made by a-device described and claimed in my co-pending application for a patent on improvements in recorders. Serial No. 697.459. filed Mav 15. 1912. This application has since resulted in Patent No. 1,105.906, granted August 4, 1914.

So far as is necessary to an understanding of the present'invention, that'machine may be said to comprise a cylindrical record drum rotated by some moving object, such as a float and a recording stvlus bearing against the cylindrical face of the drum and propelled along an element thereof by a clock mechanism. The record made bv this device is traced on a plurality of contiguous short strips of paper each `mounted on the periphery of the drum by insertingL its ends through slots therein and clampingthem to radial springs within the drum. Theresulting record consists of a 4series of separate sheets of paper each having adjacent its vends transverse creases caused by drawing the paper sheet through the slots. and each bearingr a portion of a continuous record plotted between time and position of the ob- Iiect. 'The record sheets are devoid of all coordinate lines and the present device is intended to interpret the record sheets by accurately positioning them with reference to two graduated scales according to their former position on the drum. For this purpose advantage is taken of the aforementioned creases, which beingcaused bv drawing the ends of the sheets through the slots form an accurate index ofthe position of the sheet on the drum.

Additional features of my present yinventionrelate to the `adaptation of such a measuring device to the measurement of records from machines having diEerent drive ratios y Specification of Letters Patent.

between the moving object and the recording drum.

I have successfully embodied the i'nvention in a device for interpreting records each section of which has an effective length of six inches, and this is illustrated in the accompanying drawings, V1n which" Figure 1 is a plan view of the complete device, certain parts being broken away, and the record sheet being shown mounted yin position; Fig. 2 is a section on the line 2-2 of Fig. 1; Fig. 3 is a section on the line 8-3 of Fig. 1; Fig. 4 isa perspective view of the sliding carriage and the rotatable scale bar;

Fig.` 5 is a perspective view ofl the record support and the rotatable scale bar mounted thereon; and Fig. 6 is a plan view of a portion of a modified form of record sup- .f

, Referring to thedrawings 1 represents the base plate which is preferably made of sheet sheet of paper. The plate 4 is attached to the base plate 1 only at its rear edge Vand upon its 'upper face along the line of attachment and parallel to the edge of the bar 3 is a raised straight edge 5, which is intended to serve as a guide in positioningthe record sheet. This record sheet, as indicated at 6 in Figs. 1

and Q-consists of a strip of paper having transverse folds or creases 7, adjacent its ends, and the record sheet is mounted in the device by placing it upon the plate 4 with its `ends folded under the plate and lying between it and the base plate 1, the'record sheet being pushed up against the straight edge 5 to position it in parallelism with the bar 3. These record sheets accurately lit the plate 4 having been properly creased by their previous mounting in the recording devicelmentioned, so that the position of these creases serves to position the record sheet longitudinallyiwith reference t9. the vscales fil Patented Mar. 14, 1916.

on bar. The record consists of an irregular line 8 traced bythe recording device as will be apparent from an examination of my patent above referred to. Y

In Fig. G l illustrate an valternative-coni struction in which a separately formi-id'platey 4' is dispensed with. In this case .the plate` l is provided with two parallel slots 9 which are spaced apart a. distance equal to the length of the record sheet between its creases. A straight edge 19,:similarin form and function to the straight edge 5, is used. The :record is mounted in .the ydevice by inserting its ends through the slots .9 and folding `them ltoward each vother at .the creases. That @portion lof the platel lying .betweenthe slots 9 .takes the place ofthe separately formed plate ,4 used in the preferred construction and `retains :the :record in the same manner. Y

vThe bar 53 serves as a guide' Afor Ia ilongitudinallyumovable carriage Vl'l, .which vconsists cfa guide frame l2 straddling and aguided .by the bar .3. It is 'guided by direct contact -with :the forward face of the'bar :3 .and is fheld* '.resiliently in engagement therewith bv a bowspring 18 vas clearly shown in Fig. r1. .The carriage l1 is provided e-with :al "forwardly-extending bracket 14 ,having slots 1.5 at right angles yto :the line of movement of the carriage and consequently at right :angles `to the lbar 3. A transverse scale i116 .graduated .in hourse :of time is adjfustably mounted upon the carriage lil by :means .of set screws '17 passingy through the.. slots 15, I4and i thisy scale is so mounted' as vto slide-closely yover .the face -of the record. `The .purpose of the slots 15 lis vto permit fan accurate :adjustment of vthe scale with reference t0 the actual time interval during which the `record vwas taken :so ithat the Escale may be adjusted to ireafd .in lhours ldirectly. hThe scaleofspacing ofthe graduations- -o'if this .time Vscaled- 6 is `wholly :dependent 'upon -the r-ait'e 4of. feed vof Vthe `record'- eing 4pencil by .fthe clock "forming a apart of the :recording .devicewhose .records 4are .to be interpreted. The purpose of rotatably mounting the rbar .i3 lis to permit different faces of the bar '3 Vprovided 4'with different :forms of graduations. Ato be :brought into coineratiif'e :relation with the index edge 18 of the `carriage k11. For instance `.the scale A shown in Fig. :2. is used to measure ythe records ofia recording device fin which ythe movements-of a bod-v are recorded Vin .hundredths lof a foot `and :in which the record .is vmade full 4si7e.- The range of lthis scale ,is from 0 .to V0.5 foot, While -scale B "shown 'in Fig. l is used -to ymeasure similarl records, but isint-ended :for measuring the sections `thereof lying between lfoot and 1.0 foot. The scale Cshown .in Fig. '5 isgraduated Vin hundredths of Ia foot and `is, intended for interpetingreserds @machinerie which the scale of record is one fourth size. The range of one section of a six inch record is therefore 2.0 `feet as clearly indicated .in Fig. The device is therefore available to interpret records made -by various ma- Ichines-having diderent drive ratios between .the record drum and the moving body whose movements are recorded, and by increasing the number of faces on. the bar 3 a larger number of scales might be embodied in a .single instrument though I have found the form shown to be satisfactory for ordinary purposes. j L

V'ln the useof the device the .record vsheet :is mounted .in the machine 'in one of the 4ways above .described according to the `form of the machine. so .that the `Aappropriate graduated :farce :is at the top. Thefcarriage l1 isthenslipped into place. The scale 16 yis :then :adjusted -so that ythe proper hour on the scalefcoincides with a .line -19 which is marked fon `the record,sheet` at the time therecord is started. -Invthe example illustrated :for instance the Llgraduation is placed in registry 'with Ithe line marked e a. in. The corresponding The bar r3 is then turnedVv position of the lobject whose positions are;

recorded be Vthen read `for any desired :time yby moving the 'carriage 11 alongthe bar 3 until the :desi-red :time graduation --coincides with'the recordlineS. Forinstance inftheexample illustrated atf-Sfgaem.- on May .10th, Athestage Vwas 0.90 .footLas indicatedat the point marked Din Fig.l. f

In ,all ordinary positions ythe `scale 16pxftends lbeneath the Iba-r .3 and `'this serves .to

prevent `any .accidental displacement '.of .the

.carriage as vthe device is in use'.`

' YA particularly important feature .of my rinvention.is the fact .that the record sheet is positioned in the :device by means :of `'creases' made VVin the record -sheet by .the act of y'placing it upon the record drum, Icon.- `seduently these creases serve as an :accurate means for positioningthe sheet in the Ineas-v `urina devices` and 'all cordinate rulings and graduatiens of .the .record sheet .becomev i1.
